I'm in a dilemma. I've had for offer an MZ-N1 for $400 AUS, (halve for $US), or an MZ-N505 for $450. The problem is, the MZ-N1 unit I'm being offered is missing the charging cradle, power adapter and all the stuff that connects to the cradle (bar the MD unit itself). How much would a replacement cradle and all the gear cost, and is the MZ-N505 as good as the MZ-N1?
